Sequence rules for R and S nomenclature

Sequence rules give the ranking order for the groups attached to chiral carbon in order to assign R or S configuration to that carbon. Mainly three sequence rules are defined to rank the groups in priority order.
0:00 Introduction
0:14 Why they are required?
0:54 Sequence rule 1
1:58 Example 2
4:50 Sequence rule 2
6:33 Example 3
8:46 Sequence rule 3
9:34 Example 5

[@souradeepdey1338]

Sir plz tell me if with the chiral two carbon are attached lets say c1 and c2 and in c1 there is cl,c,c,H and in c3 there is double bonded O and H when which will have higher priority c2 or c2?

-COOH, OH which has more priority?
OH right?

Exactly, -OH is given more priority than -COOH.

Ex 4 ma oxygen ko 1no. milna tha na

[@egpat]

Exactly ! Oxygen is given more preference than nitrogen

[@san_ia]

Is example 4 wrong?cause oxygen should be given the priority

[@egpat]

Example 4 is correct. While we give ranking we have to consider the first atoms directly attached to chiral carbon. So here they are -NH2, -CH3, -COOH and H. Among these nitrogen is given preference than carbon. Now competition is in between -CH3 and -COOH. Then we have to expand the group and compare further groups attached. So, -CH3 has three hydrogens (H,H,H) whereas -COOH has three oxygens (O,O,O). Therefore -COOH is given preference than -CH3. Hope now its clear at this example. Thank you for watching this video.

[@santhoshib6734]

Lower priority group that should be placed in bottom naa

[@egpat]

It should be on the vertical line, but it will be easy to assign configuration when the lowest priority group is at the bottom.
